Inline if using c#

Hi Experts,

I have  to display fields in UI based on Field setting file. In this file we can set each field to some value (0,1,2,3,4 etc) and retrieve this information and will show/hide/do something for the field in the UI. For instance to display a Name field it has just 2 values (0 and 1). Here is the code using inline if statement that will check if it is set to 1 or 0.

FieldSettings.cs

//ToDisplayName

0=show
1=HIDE

Public bool IsDisplayName
{

get

{
  int? paramvalue=Getvalue();

  return paramvalue.Hasvalue && paramvalue.value=1?true:false


}

}

Open in new window



Class1.cs


//Checking condition for ToDisplayName or Not

FieldSettings Prjconf=new FieldSettings();

if(Prjconf.IsDisplayName)
{
//do something
}

else
{
//do something
}

Open in new window


Similarly I have below  fields that have 3 and 4 values.I am confused if I should return bool or int and how to write them using inline (Fieldsettings.cs) and retrieve this information in class.cs file.

ToDisPlayAge(3 values)

0=No
1=Yes-Hide
2=Yes-Show

ToDisplayMobile(4 values)

0=Hi
1=Hello
2=welcome
3=Thank you

Me too, I became very confused :)
i did not get how and why "ToDisplayMobile" will return "welcome" or "Hello"

my advise is to use strong typing and user structures as datatypes for those values
since you using full coding block then no need to inline if just make your code clear
using if blocks

In place of inline if, you could use a function call like:

This way you can have as many options you like. You need to make it work with your project.

     private void button1_Click(object sender, EventArgs e)
        {
            MessageBox.Show(FindResponse(0).ToString());
        }
        private string FindResponse(int indx)
        {
            string msg="";
            switch (indx)
            {
                case 0:
                    msg = "Hi";
                    break;
                case 1:
                    msg = "Hello";
                    break;
                case 2:
                    msg = "Welcome";
                    break;
                case 3:
                    msg = "Thank you";
                    break;
            }
            return msg;
        }

You add one simple function and that is it. I think it is simple all right. Inline if never can handle more than two.

Instead of:

return paramvalue.Hasvalue && paramvalue.value=1?true:false

use:

return paramvalue.Hasvalue && FindResponse(1)

You're making things more complicated than they are.
1) About the conditional operator.
This:
xx ? true : false

Open in new window

is exactly the same thing as
xx

Open in new window

2) About nullable types
This:
xx.HasValue && xx.Value == yy

Open in new window

is nearly the same as
xx == yy

Open in new window


In short, this
return paramvalue.Hasvalue && paramvalue.value==1?true:false

Open in new window

can be rewritten as
return paramvalue == 1

Open in new window
